I am applying to Cambridge this year and currently have 4 5s (Comp sci A, Calc AB, Physics C, and statistics) as well as a few other 4s and one 3. I know that you can include predicted AP scores in your reference, but I am taking 5 AP exams in my senior year. I would like to get my teachers to predict my AP scores and have them report to Cambridge. Would I be able to send in all of my predicted scores or just one? Additionally, does my reference have to be one of the teachers to send in my predicted AP scores?
